Title: Internally oxidizing method for silver alloy fine grain
Inventor: EZAWA NOBUYASU
IPC: B22F1/00
Filed: 1978-10-16
Abstract: PURPOSE: To internally oxidize silver alloy fine grains as an electrical contact point material with high efficiency by charging the grains into a hermetically sealed furnace; evacuating the furnace; filling oxygen gas into the furnace; and heating the grains.  
     CONSTITUTION: Fine grains of an alloy such as Ag-Sn or Ag-Cd used as an electrical contact point material are charged into a hermetically sealed container made of Ag. This container is placed in a heating furnace and evacuated at such a temp. as will not oxidize the Ag alloy. After being filled with oxygen gas, the container is heated in the furnace to internally oxidize the grains. Since the container is evacuated once, nitrogen gas, etc. in air adsorbed on the grain surfaces are removed, and the oxygen gas well reaches the grains. Accordingly, the internal oxidation is performed thoroughly. Even if the grains are piled up, all of them are internally oxidized, resulting in enhanced productivity.

IPC: G11B21/10
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To compensate track eccentricity of a high frequency by controlling a magnetic head position by the eccentricity compensation signal calculated by using the parameter determined in accordance with the transmission function from a voice coil operation signal to a magnetic head position error signal and the detected position error information. SOLUTION: As a procedure to determine the parameter, a switch 21 is connected to a test signal generator 9 and a test signal 23 consisting of a specific frequency +α is first inputted as a voice coil operation signal 19. An eccentricity compensation parameter calculator 10 makes the Fourier analysis of the position error signal 14 and determines a gain TA1 and phase difference TB1 at the specific frequency +α. Next, the calculator is inputted with a test signal 24 of a specific frequency -α from a test signal generator 9 and determines a gain TA2 and phase difference TB2 at the specific frequency -α. The interference of the track eccentricity is removed by the linear interpolation of the gain TA1, 2, TB1, 2, by which the transmission function from the voice coil operation signal 19 to the position error signal 14 is obtd.

Abstract: PURPOSE:To automatically switch an input from a MUSE/NTSC converter by discriminating whether a satellite broadcasting is in a MUSE system or an NTSC system at the television receiver equipped with two input parts for a standard signal and a double speed signal. CONSTITUTION:The output of a synchronizing phase comparator circuit 15 shows whether the satellite broadcasting is in the MUSE system or the NTSC system, and is inputted to the respective control terminals of a selecting circuit 20 and a CRT driving circuit 21. When the broadcasting is in the MUSE system, the circuit 20 selects the double speed video signal inputted from an input terminal 18. When the broadcasting is in the NTSC system, a double speed video signal 17 of non-interlace from an EDTV processing circuit 16 is selected, and the output is supplied to a CRT 22. In the case of the MUSE system broadcasting, the circuit 21 drives the CRT 22 based on a double speed synchronizing signal from an input terminal 19 and in the case of the NTSC system broadcasting, the CRT is driven by a standard synchronizing signal 14 separated at a synchronizing separator circuit 12. Thus, the inputs from the MUSE/NTSC converter are automatically switched and received.

Title: Buffer device
Inventor: KADOTA HIROSHI
IPC: G11C15/04
Filed: 1987-05-25
Abstract: PURPOSE:To reduce the congestion of an IO part by using associative memories having retrieving functions to form address memory elements serving as two pairs of memory elements which store data and their corresponding address information and reading out the data storage contents of the position of coincidence between the retrieving results. CONSTITUTION:In case an access is applied to the data buffered by a data memory part 3 from the CPU side, the relevant address information is applied to an address information memory part 1 via an input circuit network as the retrieving information. The part 1 consists of an associative memory which can detect the coincidence between the memory contents and the applied information. If the coincidence is detected with a certain word, an output command signal is transmitted to the part 3 at the same position as the position of said word from a coincidence detection line at said position. Then the data received an access toward the CPU is outputted from the part 3. Thus it is possible to store temporarily and read out the data and addresses as well as to retrieve and read out the address information on the stored data.

Title: Pll circuit device
Inventor: HARUKI HIROSHI
IPC: H03L7/107
Filed: 1984-06-21
Abstract: PURPOSE:To quicken a lock speed by selecting a time constant of a low pass filter at the unlock state so as to be minimized for the lock time and changing over the said time constant at the lock state so as to minimize an FM noise. CONSTITUTION:When a PLL loop is in the unlock state, a discriminating circuit 6 detects the state and controls changeover switches 7, 8 so as to connect a low pass filter 4 between a phase comparator 1 and a VCO2. The low pass filter 4 consists of a lag/lead filter where the time constant is selected so as to attain the unity of the damping coefficient, and even if the FM noise is increased, the lockup time is decreased. When the PLL loop transits to the lock state, the discriminating circuit 6 detects it, the changeover switches 7, 8 connect a low pass filter 5 having a damping coefficient of nearly 0.3 so as to decrease the FM noise and improve the performance. Thus, the lockup time is reduced without deteriorating the performance.
